BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a pixel unit, pixel array, multimediadevice, and a manufacturing method thereof, and more specifically, thepresent invention relates to a pixel unit, pixel array, and multimediadevice with a display medium module and a manufacturing method thereof.

2. Description of the Prior Art

With the advancement of technology and time, users are getting moredemanding about visual display and voice, and require multimedia deviceswith the advantages of compactness, high contrast, high dynamic, highcolor saturation, high aperture ratio, large-sized panel, low cost andlow power consumption, high quality, multi-faceted display, easymaintenance and good sound quality and other advantages of multimediadevices.

The display part of the current multimedia device can be divided intoself-luminous and non-self-luminous ways to achieve the function ofimage display, and the liquid crystal display is the main way ofnon-self-luminous flat panel display device, wherein the amount of lightpassing through a liquid crystal medium is modulated by controlling thevoltage of the upper and lower electrodes of the liquid crystal medium.The effect of color display is achieved with further employment of acolor filter layer, a polarizer and some functional optical films, andbacklight, etc.

Self-luminous flat panel display may be categorized into field emissivedisplay, plasma display, electroluminescent display, organiclight-emitting diode display and so on. In an organic light-emittingdiode display (OLED), light-emitting polymers are deposited between anupper electrode layer and a lower electrode layer. With furtheremployment of a conductive layer of electrons and holes, and lightdisplay is generated by adding the electric field to move the carrier,resulting in electrons and the hole carrier recombination phenomenon. Incomparison, an organic light-emitting diode display device ischaracterized by its wide viewing angle, fast responding speed, thinpanel and flexibility; further, it requires neither backlighting norcolor filter and may be made large-sized.

The display panel of both LCD and OLED devices has a plate oftransparent glass for a substrate, directly and sequentially forming athin-film transistor, a lower electrode layer, a display medium layer,an upper electrode layer and others thereon. The thin-film transistormay control the voltage or current imposed on the upper electrode layerand/or the lower electrode layer to control the state of the displaymedium. Since it is necessary to directly and sequentially forma thinfilm transistor and an electrical conduction pattern on the glasssubstrate, whereon will be relatively compressed the effective area ofpixel unit, and difficult to achieve high aperture rate of pixel unit.

Referring to FIG. 1, a top view of a known pixel. Pixel unit 1PP mayserve as part of a display panel (not shown in the drawing) fordisplaying a pixel part of an image; generally, the pixel unit 1PPincludes a glass substrate 10S, and a gate control line 11G, a datacontrol line 12D, a thin film transistor 13T, and a pixel electrode14PE, and a common display medium and a pixel corresponding electrode(not shown), are sequentially set up on the glass substrate 10S. Thethin film transistor 13T has a gate, a source, and a drain,respectively, electrically connected to the gate control line 11G, thedata control line 12D, and the pixel electrode 14PE, for controlling thestate of the display medium, and adjusting the luminous flux of thepixel electrode 14PE. If the use of organic light-emitting diode (OLED)for the display medium, more thin film transistors and capacitors areneeded. In addition, in order to embed the touch function, the pixelunit needs to add more signal control lines, and thus more compressedthe pixel electrode (light through) the area. Furthermore, each pixelunit 1PP of the display panel is integrally formed with the same glasssubstrate 10S, the signal control line, the display medium, the pixelcorresponding electrode, and it is not easy to replace or repair thepixel unit 1PP which is individually damaged. The larger size of thedisplay demands the bigger range of the glass substrate needed to formthe thin film transistor 13T (i.e., the array of the thin filmtransistor 13T has a large area), it is difficult to control theuniformity for the thin film transistor 13T of the pixel unit 1PP (Suchas threshold voltage, current drive capability), the required processequipment becomes expensive, the process becomes complicated, themanufacturing time becomes longer, the cost is higher, the massproduction quality and the yield control are less stable and moredifficult to accomplish controlling of multi-layer display media and themanufacture of multi-facet display and repair part of the damageddisplay device.

The frame of display section on the existing multimedia device isrefreshed every time must be combined the drive circuit element, locatedat the periphery of the display pixel unit 1PP, to sequentially drivethe thin film transistor 13T of each pixel unit 1PP, and to update andwrite the content of each pixel unit 1PP, which is easy to cause powerconsumption issues. To combine the parts of the sound, it is usuallynecessary to additionally assemble the loudspeaker (speaker), resultingin a complex system with high cost and thinning more difficult.

In view of the foregoing, existing multimedia devices still have variousdisadvantages to overcome.

Thepixel unit 1PU may serve as part of a multimedia device (not shown inthe drawing) having a display function to display a pixel part of animage; that is, a display function device may include one or a pluralityof pixel units 1PU according to the present embodiment. The pixel unit1PU may include an active switching element 116, a display medium module1U and other elements. The active switching element 166 may be used tocontrol the state of the display medium module 1U to further control theamount of light passing through a display medium module 1U (ormodulating the properties of light). More specific technical contentswill be illustrated below.

Please refer FIG. 2A to FIG. 2F, showing cross-section views of thedifferent constructed pixel units along the line A-A′ line of FIG. 2A.an active switching element substrate portion 166S and a transistorportion 166T formed on the active switching element substrate portion166S. That is, the wafer portion 166T is a part of an active switchingelement substrate (not shown in the drawings). which may be glass,quartz, metal, metal oxide, silicon, silicon dioxide on insulator,germanium, gallium arsenide, gallium nitride, three-five compound,two-six compound, four-four compound, four-four alloy, amorphoussilicon, organic flexibility, inorganic and the combination of the above(silicon wafer is used in the following illustrations), and thetransistor portion 166T is formed by a series of semiconductor processes(exposure, development, etching, diffusion, deposition, ionimplantation, cleaning, inspection, etc.) on the active switchingelement substrate. The active switching element substrate may besimultaneously formed with a plurality of the transistor parts 166T, andthen the active switching element substrate may be divided into aplurality of portions (with each part including one or more transistorportions 166T) by a cutting process, and each part is the activeswitching element 166 described above. In addition, the active switchingelement 166 may further include a plurality of electric conductors 166Cand a plurality of electrodes 166E formed on and/or in the upper andlower surfaces of the active element switch substrate portion 166Sand/or the transistor portion 166T, The source, the gate, and the drainof the transistor portion 166T may be electrically connected to eachother. The active switching element 116 may also be regarded as a chipor die.

The display medium module 1U comprises at least one pair of electrodesand a display medium 105. The pair of electrodes includes a firstelectrode 101PE and a second electrode 102RE, and the first electrode101PE and the second electrode 102RE are separated from each other andmay face each other. The display medium 105 is disposed between thefirst electrode 101PE and the second electrode 102RE. The firstelectrode 101PE and the second electrode 102RE may also be referred toas a pixel electrode and a pixel corresponding electrode, and may be anon-transparent, partially transparent and/or transparent electrode(e.g. formed of a metal oxide, a nano silver wire, a conductive polymer,carbon nanotubes and graphene). Electrical energy may be imposed on thefirst electrode 101PE and the second electrode 102RE to change themagnitude and/or the direction of the voltage, current, inductance,capacitance, electrical field, and magnetic field between the firstelectrode 151 and the second electrode 153 and one of the combinationsthereof.

The first electrode 101PE may also be electrically connected to theactive switching element 116 (e.g. via the electrode 116E of the activeswitching element 116 and/or another set of electrical conductors 118).The active switching element 116 may control whether electrical energyis to be imposed on the first electrode 101PE and/or the secondelectrode 102RE.

The display medium 105 may also be called light modulation medium.

Specifically, the active switchingelement 116 may control the electrical energy imposed on the firstelectrode 101PE and/or the second electrode 102RE, causing the voltage,current and electric field and so on between the first electrode 101PEand the second electrode 102RE to change, which causes the state of thedisplay medium 155 to change. In the case of a display medium 105 madeof non-self-luminous liquid crystal, change in the state of the displaymedium 105 means torsional rearrangement of the liquid crystalmolecules. In the case of a display medium 105 made of self-luminousorganic light-emitting diode, change in the state of the display medium105 means by the applied electric field size to move the carriers forinducing the electrons and the holes carrier recombination phenomenon,to produce light intensity and color.

The activeswitching element 116 may be disposed on the first substrate 101PSand/or the second substrate 102RS, but not directly manufactured on thefirst substrate 101PS and/or the second substrate 102RS; that is, theactive switching element 116 is independent after separatelymanufactured before being assembled to the first substrate 101PS and/orthe second substrate 102RS. Further, the active switching element 116may be disposed on one of the upper and lower surfaces, the inside, thegroove 109GV, the perforation 109TV, and the combination of the firstsubstrate 101PS and/or the second substrate 102RS, so that the pixelaperture ratio of the first electrode 101PE is less compressed by theactive switching element 116.
